The whistleblower website Wikileaks has published another set of hacking tools belonging to the American intelligence agency CIA. The latest revelation includes a user guide for CIA's 'Weeping Angel' tool... derived from another tool called 'Extending' which belongs to UK's intelligence agency MI5/BTSS, according to Wikileaks. Extending takes control of Samsung F Series Smart TV. The highly detailed user guide describes it as an implant 'designed to record audio from the built-in microphone and egress or store the data.'

According to the user guide, the malware can be deployed on a TV via a USB stick after configuring it on a Linux system. It is possible to transfer the recorded audio files through the USB stick or by setting up a WiFi hotspot near the TV. Also, a Live Liston Tool, running on a Windows OS, can be used to listen to audio exfiltration in real-time. Wikileaks mentioned that the two agencies, CIA and MI5/BTSS made collaborative efforts to create Weeping Angel during their Joint Development Workshops.
